Plus it's too long. The best couch gags are, IMO, the ones that are normal length, or at least close to normal length.
My faves:
-9F02: The family runs off the screen, past the edge of the film.
-1F14: The family has to split in half to sit on two separate couches.
-1F18: Homer rips off the Fox logo and the family stomps on it.
-2F06: The family runs at the couch but never make it because the perspective changes, as the couch gets farther and farther away and they stay the same distance away.
-3F09: A hunter has all the Simpsons heads mounted on the wall.
-3F10: Miniature mouse family in the wall mirrors the regular family.
-4F07: Vend-a-Couch. Homer repeatedly hits the button until a couch falls on him.
-4F08: Whack-a-Mole game, with Homer being hit by the mallet.
-4F11: America Onlink window, with a status bar that takes forever to load the family. Finally the aggravated user hits cancel repeatedly.
-3G03: The family doesn't make it to the couch because everyone is locked outside.
-5F23: The family is tiny, and they lift each other up onto the couch. But then Santa's Little Helper comes in and grabs Homer.
-3G04: Rocky and Bullwinkle parody.
-AABF13: Adult Bart and Lisa. Homer wants to use the remote but Lisa takes the remote from him and slaps his hand.
-DABF10: Matt Groening as puppet master.
-DABF20: "Get Smart" parody, with Homer going through all the futuristic doors.
-EABF18: Everyone decays into dust.
-FABF16: "What? Can't we sit on the couch without something happening?" And then a spear is thrown at Homer.
-HABF01: "COUCH GAG THRILLS NATION"
